|ece3648-sup-0001-TableS1.docx||Word document||28K||Table S1. Raw model outputs of the flower abundance models as presented by the R software. Fixed effects show which covariates and interactions of the full model flowers ~ regime * year (+cover where appropriate) remain in the minimal model. Phi is an autocorrelation term included due to potential reproductive trade-offs from previous seasons. Model selection was done by step-wise removal of non-significant terms, until all higher order terms were significant. Only minimal model outputs are shown, that is after model selection. See main text for details about the all-years and all-regimes models.|

Air and soil surface temperatures at 1 cm depth in Shallow, Normal, Medium and Deep snow regimes in years where data of all regimes were available. Vertical lines show average melt out dates of all observed snow regimes. Air temperatures show daily averages at Longyearbyen airport, Svalbard obtained from the Norwegian Meteorological Institute, and soil surface temperatures show daily averages measured in each snow regime with a total of 24 loggers. Normal: unmanipulated snow depth as found representative for most of the study area; Deep: manipulated snow depth with snow fences; Shallow: unmanipulated snow regime shallower than Normal as found on slightly elevated ridges throughout the study area; Medium: increased manipulated snow regime shallower than Deep. Note that temperature data from Shallow and Medium are from only three of the 12 observed plots.|
